Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, and in particular to an oblique angle measuring instrument. Background Technology

[0002] Measuring the bevel angle of a mold is a crucial quality control step in mold manufacturing and maintenance, ensuring product accuracy and functionality. The bevel angle refers to the tilt angle formed by the surface of a mold part relative to a reference surface. It is commonly found in various molding dies, such as plastic molds and die-casting molds. The tilt angle is typically measured using specialized measuring tools, such as angle gauges, universal protractors, or coordinate measuring machines (CMMs), which provide accurate angle data to help detect any deviations that may affect the quality of the final product.

[0003] In measuring the angle of the inclined plane of a mold, manual measurement is a direct and low-cost method. However, the accuracy of manual measurement is limited by the operator's skills and experience, and there may be significant differences between different personnel, which leads to a decrease in the consistency and reliability of the measurement results.

[0005] This utility model is achieved through the following technical means: an oblique angle measuring device, including a support plate and a measuring ruler, the measuring ruler being rotatably mounted on the support plate, and also including a fixing ring, a protractor and a pointer, the fixing ring being fixedly connected to the upper right part of the support plate, the protractor being fixedly connected to the front side of the fixing ring, and the pointer being fixedly connected to the front side of the measuring ruler, with the pointer located above the protractor.

[0006] Furthermore, it also includes a first knob, a first screw, and a support base. The support plate has a first screw threadedly arranged on both the left and right sides. The first knob is fixed to the top of the first screw, and the support base is fixed to the bottom of the first screw.

[0007] Furthermore, it also includes a second knob, a second screw, a fixed plate, a guide rod, a moving block, and a connecting rod. The fixed plate is fixedly attached to the support plate and is located to the right of the measuring scale. Guide rods are symmetrically fixedly attached to the fixed plate. A moving block is slidably arranged between the two guide rods. A second screw is fixedly attached to the right side of the moving block and is threadedly connected to the fixed plate. A second knob is fixedly attached to the right end of the second screw. A connecting rod is rotatably arranged on the moving block and is rotatably connected to the measuring scale.

[0008] Furthermore, it also includes a fixing block and a level. The fixing block is fixed to the top of the support plate, located in front of the fixing plate, and a level is fixedly installed on the fixing block.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] A bevel angle measuring device, see Figures 1-5 As shown, it includes a support plate 1, a measuring ruler 2, a fixing ring 3, a protractor 4, a pointer 5, a protective shell 17, and a pressure plate 18. The measuring ruler 2 is rotatably mounted on the support plate 1. The fixing ring 3 is welded to the upper right part of the support plate 1. The protractor 4 is fixed to the front side of the fixing ring 3. The pointer 5 is fixed to the front side of the measuring ruler 2 and is located above the protractor 4. The protective shell 17 is fixed to the fixing ring 3, and the protractor 4 is located inside the protective shell 17. The pressure plate 18 is fixed to the left side of the measuring ruler 2.

[0022] When using this device, the operator places it in the designated position, then rotates the first knob 6 to rotate the first screw 7. The rotation of the first screw 7 moves the support base 8 downward to a suitable position, thereby adjusting the height of the device. This facilitates the operator's continued measurement of different molds. The operator then rotates the measuring ruler 2 to rotate the pressure plate 18, making the pressure plate 18 contact the inclined surface of the mold. Under the action of the pressure plate 18, the contact area is increased, improving the accuracy of the test value. The operator then observes the value indicated by the pointer 5 on the protractor 4. Under the action of the protractor 4, a more accurate value can be obtained, further improving the accuracy of the value. The protective shell 17 protects the protractor 4 from damage caused by external forces. After completing the measurement, the operator reverses the measuring ruler 2 to return the pressure plate 18 to its original position. Repeating the above operation allows for the next oblique angle measurement.

[0023] Example 2

[0024] Based on Example 1, see [link to Example 1] Figure 1 and Figure 4 As shown, it also includes a first knob 6, a first screw 7 and a support base 8. The support plate 1 has a first screw 7 symmetrically threaded on both the left and right sides. The first knob 6 is fixed to the top of the first screw 7 and the support base 8 is fixed to the bottom of the first screw 7.

[0025] When the pressure plate 18 contacts the inclined surface of the mold, the operator rotates the second knob 9 to drive the second screw 10 to rotate. The rotation of the second screw 10 drives the moving block 13 to move to the left, so that the moving block 13 drives the connecting rod 14 to rotate, thereby fixing the position of the measuring ruler 2. This prevents the angle of the measuring ruler 2 from easily changing during measurement, which would lead to inaccurate measurement values. After the measurement is completed, the operator reverses the second knob 9 to reset the second screw 10, the moving block 13 and the connecting rod 14. The above operation can be repeated to fix the measuring ruler 2 for the next time.

[0026] See Figure 1 and Figure 5As shown, it also includes a second knob 9, a second screw 10, a fixed plate 11, a guide rod 12, a moving block 13, and a connecting rod 14. The fixed plate 11 is bolted to the support plate 1 and is located to the right of the measuring ruler 2. The guide rods 12 are symmetrically fixed to the fixed plate 11. The moving block 13 is slidably arranged between the two guide rods 12. The second screw 10 is fixed to the right side of the moving block 13 and is threadedly connected to the fixed plate 11. The second knob 9 is fixed to the right end of the second screw 10. The connecting rod 14 is rotatably arranged on the moving block 13 and is rotatably connected to the measuring ruler 2.

[0027] See Figure 5 As shown, it also includes a fixing block 15 and a level 16. The fixing block 15 is welded to the top of the support plate 1. The fixing block 15 is located in front of the fixing plate 11, and the level 16 is fixedly mounted on the fixing block 15.

[0028] When the device is placed in the designated position, the staff can observe the level 16 to determine whether the support plate 1 is in a horizontal state, thereby improving the rigor and accuracy of the test of this measuring instrument.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
